Same as with previous version you sent. The function returns pointer directly, so let's test for that, instead of string comparison.
Sorry, but I really have no idea what you mean by that. I can't find a test that has an example of what you're talking about. Can you please provide an example of what you mean? Also, does this mean the test for PropVariantToStringWithDefault is wrong?
Another useful test would be with default_value == NULL.
Indeed, thanks. -- Kind regards, Mohamad
